Abstract
The system of Integrated-Optics Acousto-Optic RF Spectrum Analyzer (IOAOSA) consists of a laser diode, an Acousto-Optic (A-O) modulator, geodesic lenses and CCD detector array. The optical signal projected on the CCD array is converted into electrical signal and processed by the signal processing center which consists of a TMS 32010 system and an IBM-PC. The TMS 32010 with very high speed is used in a microcomputer system. A cycle sample method is adopted to collect the data of the CCD video signal, sampling one per 40-point. After the processing, the frequency bandwidth, the resolution and the dynamic range of the system are measured to be 100 MHz, 8 MHz and 20 dB, respectively.
